... and having a stent placed in the "distal circ" area of my heart. While in the hospital my blood pressure ran low and were times that the hospital staff did not give me this medication because my blood pressure was too low. When I take my blood pressure before taking this medication at times is like 95 to 101 over 55 to 70. I was told not to take the medication if my blood pressure was below 100 / 50. my question is ... what should my blood pressure be before I take this medication? I am only prescribed 2.5 mg daily. I am also prescribed 75 mg plavix and an 81 mg ecotrin (aspirin) and Lipitor for Cholesterol.
